Determinants of sedentary 24-h energy expenditure: equations for energy prescription and adjustment in a respiratory chamber.

ABSTRACT:

Background

Achieving energy balance is critical for the interpretation of results obtained in respiratory chambers. However, 24-h energy expenditure (24EE) predictions based on estimated resting metabolic rate and physical activity level are often inaccurate and imprecise.

Objective

We aimed to develop and validate equations to better achieve energy balance in a respiratory chamber by adding or subtracting food items.

Design

By using a randomized data set with measures of 24EE (n = 241) performed at the Pennington Biomedical Research Center, we developed equations to predict 24EE from anthropometric, demographic, and body composition variables before and at 3 and 7 h into the chamber measurement. The equations were tested on an independent data set (n = 240) and compa
